WILLIAM N. HALL, OF NEWARILNEW' JERSEY.

BELT|NG.

SPECIFICATION forming part of Letters Patent No. 259,137, dated June 6, 1882.

Application filed March 31, 1882. (No model.)

exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain improve: ments in the manufacture of belting composed of links of leather and metal combined, the object of which is to overcome certain defects and disadvantages which have been discovered in belting of this character heretofore manufactured; and it consists in providing the heads of the fasteningpins or bolts and the nuts, or either of them, with lugs, and the countersinks in thelinks with corresponding grooves or recesses, as will be hereinafter set forth, described, and finally pointed out and embraced in the claim.

It consists in the peculiar construction, combination, and arrangement ofthe several parts, as will be hereinafter particularly set forth, and finally pointed out and embraced in the .claim.

is a longitudinal section of the same. Figs. 3.

and 4 are detached views of an outer metal link, Fig. 3 being a plan, and Fig. 4 an end view in section. Figs. 5'and 6 are detached views of a leather link, the former figure showing the edges of said link straight, and the latter figure slightly recessed or curved. Fig. 7 shows a screw-bolt with lugs on the head thereof.

Similar letters of reference indicate corresponding parts in each of the several figures.

To form the belting I employ in part scraps or pieces of old ornew leather, (either waste or good leather,) and cut them into oblong links a, of a uniform length and width, with the sides thereof either concave or parallel, as may be preferred, and their ends rounded, as

indicated in Figs. 2, 5, and 6, the thickness of the leather, as a rule, not being of much importance. Near the ends of each link holes, as a, are formed therein, as indicated in Figs. 5 and 6, through which screw bolts or rods are adapted to be inserted. The said links of leather, when thin, may be doubled or arranged in pairs. (See Fig. 1.) The edges of the leather links, instead of being parallel with each other, may be slightly curved, as heretofore set forth and shown in Fig. 6, which tends in many cases to cause abelt to hug a pulley more closely when adjusted thereon than if the edges were straight, as will be understood.

In order to strengthen the belt and prevent stretching and breaking, Iintersperse between the leather links which form the body of the belt metal links I), the samein length, but narrower and thinner than those made of leather, which may be inserted either between the double or between the single leather links in such positions as may be desired or as the case may seem to require, in order to secure the results above stated, and are provided with apertures or holes I) therein to exactly coincide with the holes in the leather links, the screwbolts being adapted to pass through both the metal and leather links from edge to edge of the belt, as plainly indicated in Fig. 1.

The object had in view in making the thin metal links somewhatnarrower than the leather links is to prevent them from coming in contact with and marrin g the pulleys over which the belt passes.

On the outer edges or sides of the belt I also place metal links 0, somewhat thicker than those in the body of the belt, but of the same length and form as the leather links, and with corresponding perforations or apertures, c, therein at the same points as in links a and b, which not only increases the strength of the belt, but protects it from injury by abrasion. The holes 0 in the outer metal links, a, are countersunk and provided with recesses a, so that the heads or nuts of the bolts, which are correspondingly tapered, may lie therein and be flush with the outer surface instead of projecting outside, as in belts heretofore in use,

which were liable to catch into articles in close proximity thereto. The links are arranged and secured together by means of screw-bolts or analogous devices, (I, in the order shown, the screw-bolts passing through the holes in the outer metal links, 0, the innerleather links, a, and metal links I), the bolts being screwed into the nuts on the opposite side from which the said bolts enter, the heads of the bolts being adapted to fit into the recesses c on the one side of the belting and the nuts being adapted to fit into the recesses in the metal links 011 the opposite side, thus fastening the links a b c firmly and securely together, and making a smooth finish, as stated. On the under side of the heads or nuts of the bolts I form lugs a, Fig. 7, which are adapted to fit in corresponding notches or groovesf in the recesses c" of the outer metal links, 0, Figs. 3 and 4, which, when the bolts are in position, prevent them from turning around and keep them in a fixed position. The tapered nuts and recesses in the links on one edge of the belt may, however, be omitted, and the links instead be screw-threaded, and the rods be screwed directly therein, it preferred, as will be understood.

I am aware that belts have been constructed of (old or new) leather links, and of leather links combined with metal links which have been connected together by metal pins.

I do not, however, wish to be understood as claiming these features, broadly; but

IVhat I claim is- In a beltcomposed of leather and metal links united together by metallic pins, the combination of the leather links at, having holes a therein, the inner metal links, b, of the same length, but narrower than said leather links, and having holes I) therein, the outer metal links, 0, the same size and shape as the leather links a, and having recesses c c,=the latter recess having grooves f therein, and the pins 01, extending through the holes or recesses in the links a b 0 from side to side of the belt, the heads and the nuts of said pins being tapered, and having the lugs e on the under side of said heads, adapted to fit in the grooves f to prevent the pin from slipping, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of March, 1882..

WILLIAM N. HALL.
